" UNITED stares I JOSEPH CYRILLE EMILE BOURASSA, OF MONTRAL, QUEBEC, ANAD.

l TRUCK.

. Application filed November 8, 1919. Serial No. 336,565.

T o all whom. z't may concern: Be it known that I'` .JOSEPH CYRILLE' EMILE BoURAssA, a British subject. residing at #1300 Bordeaux Street, in the city of Montreal, in the Province of Quebec, in thev Dominion'of Canada, have invented certain .new and useful Improvements in a Truck ,\and I do hereby declare that the followlng is a full,clear,. and exact description of the same.

The present invention relates to improvements in a truck or the like and the main object of this invention is to provide a device of this character whereby a load, which is placed' on a platform, may be lifted up and` carried away, thus saving time and labor.-

rPhe invention will be better understood with the aid of the accompanying drawings in which: i

Figure 1 is a planview of the truck ac.l cordi'ng to the invention.

Figure 2 is a side elevation of the truck in longitudinal section.'

Figure 3 is a rear end view of the truck.

Figure 4 is longitudinal section View through the rear end of the truck being shown in its raised position.

Like numerals of reference indicate corres onding parts in each figure.

n the drawings 1 is the main frame pref erably rectangurlar in shape and suitably supported on the wheels 2 mounted on the cross shaft 3, which is journalled in suit able bearings on saidl frame 1. The wheels 2 are preferably mounted adjacent one end of said frame 1 and on the other end of said frame are vprovided the' pivoted casters 4.

The frame 1 is preferably higher at one end and adapted to receive a frame 5 which may be, if preferred, of the same length of said frame 1. Oni frame 1 is rigidly Secured at one end upwardly projecting arms 6, preferably curved at their upper ends, and 7 is a cross handle secured between the outwardly projecting ends of said arms 6.

Suitably secured below said frame 5 adjacent the rear end is a bracket 8 centrally slotted at 9 and adapted to receive a pusher element 10 which slides therein.

Said-pusher element 10 is centrally perforated and provided .With a female thread and at the outer end of said pusher is;v mounted a roller 11 l'which is adapted to contact with the centrally disposed cam member 12 which is rigidi mounted on the cross-shaft 12". The saicly. shaft 12 is secured in suitable I bearings mounted in the sides of the frame 5.- This cam member 12 is so made, that it will serve as a lever against which the rollerl 11 contacts.

The cam member 12 .l1 face 12bv which is adapted, to rest against the roller 12c securedacross thevframe 1 in suitable bearings 12d. It' will readily be seen that when thef'said cam element is moved or pushed against said roller 12.l that it will force the frame .5 ..11 pwardly. Thus themost heavy 'loa/ds canibe without difficulty. j l

.At the other( end of sai 9111511521151@ 1o is provided a downward' ro ctin` pin 13 which slides in the slot provi ed-in the bottom of said brac et to regulate the travel of the pusherV 10.

S 'an eccentric SUI'L.

8 and is adapted 15 is arod which proects through one end of said bracket 8 an a worm 16 whichl is made to enga female thread in said pusher 10.

outer end of said rod a sprocket 17 which Vis operatively connected t?) the sprocket wheel 18 byv a sprocket chain mounted on the stub shaft 20 which is n the journalled in the brackets 21 secured inter-" 4mediate of the arms 6, and 22 wheel rigidly mounted at one end of said. shaft 20.

The frame 5 is mbv-ably mounted in rela-' tion to said frame 1 and the lifting motion'- 15 is rigidly mountedA is a handfis' provided with El. 1

e the The sprocket wheel 18 1s preferably,.ii

of said framey 5 is obtained by the links 23,.

and 23 whichlare disposedv obliquely when in their inoperative position andare piv otall connected at one end b the bolt 24to the rame-1 and at their'ot er end by the,V links 23 aref;y

bolt-25 to the frame 5.V The rotatabl no'unted atl thernpper ends on the sha.t .12*i and serve as gui movable frame 5.

In the operation of the invention it will' readily lie-seen that in operatingl the hand des for, the W 15 the worm 16 and the pusher 10 is' limited by' the slot 14 and 6&1-,

iiuirs -directiy connectin pin 13. and the friction between the the said pusher with the canil 12 is ed by 'the friction roller 11.

the fnnie 5 is preferably provided a twinY which is not illustrated, in the .di Winge.
